soulful sepulcher has a post up on drug interactions. You can find nearly all meds and find out the interactions as drugdigest.org. I did a search for lamotrigine (Lamictal) and venlafaxine (Effexor), which included interactions with food and alcohol and there were none. (That was a relief.) I’d encourage anyone on medication to do this search to make sure that multiple psych drugs are not interfering with each other.
